50 pht helppppppppppppppppppppppppppppppppppppppp

Answer 1

• Area=1/2(Sum of parallel sides)×Height

Area:-

`\\ \tt\hookrightarrow (1)/(2)(15+12)* 10=1/2(27)(10)=13.5(10)=135m^2`

Now rate of cost is $12

• Total cost=135(12)=1620$

Answer 2

$1620

Explanation:

The area of the lawn is a trapezoid.

Area of a trapezoid =
`\frac12(a+b)h`

where a and b are the parallel sides (bases) and h is the height

Therefore,

`area=\frac12(15+12) * 10 = 135 \ m^2`

If the price of sod is $12 per square meter, then

total cost = 135 x 12 = $1620
